Description

Technical Field

[0001] This utility model relates to the field of socket technology, and in particular to a protective structure and socket. Background Technology

[0002] The protective shutters of the socket effectively shield the socket holes, preventing the conductive strip from directly contacting the outside environment. When a foreign object is inserted, the protective shutter remains closed; it only opens when a suitable plug is inserted, allowing the plug's prongs to contact the conductive strip, thus significantly reducing the occurrence of electric shock accidents. In related technologies, the two-hole and three-hole sockets of a combination five-hole socket require corresponding double-hole and three-hole protective shutters, respectively. Due to the compact structure of the combination five-hole socket, the placement of double-hole and three-hole protective shutters is challenging, requiring more space and increasing the socket's overall size. Utility Model Content

[0003] The purpose of this utility model is to provide a protective structure and socket that combines a double-hole protective door and a three-hole protective door, thereby reducing the difficulty of layout and reducing the space occupied.

[0004] This utility model provides a protective structure, including:

[0005] The frame is provided with a receiving groove, and the bottom of the receiving groove is provided with a double socket group and a triple socket group;

[0006] A protective assembly includes a double-hole protective door, a three-hole protective door, and an elastic element. The three-hole protective door is slidably disposed at the bottom of the receiving groove, and the double-hole protective door is slidably disposed on the three-hole protective door. The two ends of the elastic element abut against the double-hole protective door and the three-hole protective door, respectively. The double-hole protective door abuts against the first end of the receiving groove and covers the double-socket assembly. When the double-socket plug is inserted, the double-hole protective door slides toward the second end of the receiving groove to expose the double-socket assembly. The three-hole protective door abuts against the second end of the receiving groove and covers the three-socket assembly. When the three-socket plug is inserted, the three-hole protective door slides toward the first end to expose the three-socket assembly. When the double-hole protective door or the three-hole protective door slides, the elastic element is compressed.

[0007] The direction of the line connecting the first end and the second end is perpendicular to the direction of the line connecting the two sockets of the dual socket group.

[0008] As a preferred technical solution for the protective structure, the three-hole protective door is provided with a base plate, which includes a large end and a small end. The large end is used to block the live wire socket and the neutral wire socket of the three-hole group. The small end is provided with a through hole, which is used to communicate with the ground wire socket of the three-hole group. The side wall of the through hole away from the large end is inclined upward and extends in a direction away from the large end to form a traction inclined wall. When the three-hole plug is inserted, the ground wire plug abuts against the traction inclined wall and drives the large end to slide towards the first end.

[0009] As a preferred technical solution for the protective structure, the bottom of the frame is provided with a support boss and a stop boss. The support boss extends along the direction from the first end to the second end. The grounding hole is provided on the support boss. The three-hole protective door is slidably disposed on the support boss. The height of the stop boss is less than or equal to the height of the support boss. The stop boss can restrict the sliding of the large end toward the first end.

[0010] As a preferred technical solution for the protective structure, a mating block is also provided on the small end, and the through hole is located on the mating block. The double-hole protective door includes a mating part and protective parts located on both sides of the mating part. The two protective parts are respectively used to block the live wire socket and the neutral wire socket of the double-socket group. The mating part is slidably sleeved on the mating block. The mating part is provided with a through hole, which communicates with the through hole. Along the direction from the first end to the second end, the upper surface of the protective part extends obliquely upward to form a pushing inclined wall. When the double-socket plug is inserted, the live wire prong and the neutral wire prong respectively abut against the two pushing inclined walls and push the double-hole protective door to slide toward the second end.

[0011] As a preferred technical solution for the protective structure, the mating part is provided with a mating groove, the mating block is provided with a mating surface, the inner surface of the mating groove can slide and engage with the mating surface, and there is a gap between the bottom of the double-hole protective door and the base plate. When the double-hole protective door and the triple-hole protective door abut against the first end and the second end respectively, the protective part and the large end are spaced apart along the direction from the first end to the second end.

[0012] As a preferred technical solution for the protective structure, the ratio between the distance between the protective part and the large end and the length of the double socket group along the direction from the first end to the second end is less than 0.3.

[0013] As a preferred technical solution for the protective structure, the bottom of the mating part is provided with a sliding groove communicating with the mating groove, and the bottom plate of the three-hole protective door is also provided with a sliding boss. The sliding boss extends along the direction from the first end to the second end. After the inner surface of the mating groove slides to disengage from the mating surface, the sliding groove and the sliding boss slide together.

[0014] As a preferred technical solution for the protective structure, the frame is provided with a limiting boss, and the double-hole protective door is provided with a first anti-detachment boss, which can cooperate with the limiting boss to prevent the double-hole protective door from falling out of the receiving groove.

[0015] As a preferred technical solution for the protective structure, the frame is also provided with a limiting hole, and the three-hole protective door is provided with a second anti-detachment protrusion. The second anti-detachment protrusion can cooperate with the limiting hole to prevent the three-hole protective door from falling out of the receiving groove.

[0016] This utility model provides a socket, including the protective structure of any of the above-described solutions.

[0017] The beneficial effects of this utility model are as follows:

[0018] This utility model provides a protective structure in which a double-hole protective door is slidably mounted on a three-hole protective door. An elastic element is provided between the double-hole and three-hole protective doors. The elastic element holds the double-hole and three-hole protective doors against the two ends of the receiving groove of the frame, thereby blocking the double-hole and three-hole socket groups. At the same time, the double-hole and three-hole protective doors can slide within the receiving groove to expose the corresponding double-hole or three-hole socket groups. This does not require excessive additional space, reduces the difficulty of layout, and helps to reduce the size of the socket. Attached Figure Description

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0036] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.

[0037] like Figures 1-9As shown, this embodiment provides a protective structure, specifically a protective structure applied to a combination five-hole socket. The protective structure in this embodiment includes a frame 1 and protective components. The frame 1 is provided with a receiving groove, the bottom of which has a double-socket group 101 and a three-socket group 102. The protective components include a double-socket protective door 2, a three-socket protective door 3, and an elastic member 4. The three-socket protective door 3 is slidably disposed at the bottom of the receiving groove, and the double-socket protective door 2 is slidably disposed on the three-socket protective door 3. The two ends of the elastic member 4 respectively abut against the double-socket protective door 2 and the three-socket protective door 3. The double-socket protective door 2 can abut against the first end of the receiving groove and block the double-socket group 101. When a double-socket plug is inserted, the double-socket protective door 2 slides towards the second end to expose the double-socket group 101. The three-socket protective door 3 can abut against the second end of the receiving groove and block the three-socket group 102. When a three-socket plug is inserted, the three-socket protective door 3 slides towards the first end to expose the three-socket group 102. When the double-hole protective door 2 or the three-hole protective door 3 slides toward the second end or the first end respectively, the elastic element 4 is compressed. Therefore, after the corresponding plug is pulled out, the double-hole protective door 2 or the three-hole protective door 3 can return to its original position under the elastic force of the elastic element 4, continuing to block the corresponding double-socket group 101 or three-socket group 102. In this embodiment, the protective structure slidably mounts the double-hole protective door 2 onto the three-hole protective door 3. An elastic element 4 is provided between the double-hole protective door 2 and the three-hole protective door 3. The elastic element 4 holds the double-hole protective door 2 and the three-hole protective door 2 against the two ends of the receiving groove of the frame 1, thus blocking the double-socket group 101 and the three-socket group 102. Simultaneously, the double-hole protective door 2 and the three-hole protective door 3 slide within the receiving groove, exposing the corresponding double-socket group 101 or three-socket group 102. This does not require excessive additional space, reducing the difficulty of arrangement and helping to reduce the size of the socket. In this embodiment, the first end and the second end are two opposite ends arranged in the receiving groove, and the line connecting the first end and the second end is perpendicular to the line connecting the neutral wire socket and the live wire socket of the dual socket group 101 or the triple socket group 102.

[0038] Optionally, to avoid the risk of electric shock caused by foreign object insertion, taking the double-hole protective door 2 in this embodiment as an example, the two sides of the double-hole protective door 2 can be configured to have a small gap between them and the two side walls of the receiving groove. When a foreign object is inserted into one side of the double-hole protective door 2, the double-hole protective door 2 tends to slide towards the second end under the action of the foreign object insertion. However, since the double-hole protective door 2 only has a foreign object inserted on one side, the force on both sides is uneven, so it also tends to rotate. Thus, the two sides of the double-hole protective door 2 abut against the two side walls of the receiving groove respectively, thereby restricting the double-hole protective door 2 from sliding towards the second end.

[0039] Furthermore, such as Figure 9 As shown, and in combination Figures 3-6The three-hole protective door 3 is equipped with a base plate 31, which includes a large end 301 and a small end 302. The large end 301 is used to block the live wire and neutral wire sockets of the three-hole assembly 102. The small end 302 is provided with a through hole 313, which is used to communicate with the ground wire socket of the three-hole assembly 102. The side wall of the through hole 313 away from the large end 301 slopes upward and extends in a direction away from the large end 301 to form a traction inclined wall 314. When the three-hole plug is inserted, the ground wire prong abuts against the traction inclined wall 314 and drives the large end 301 to slide towards the first end. Specifically, when the three-prong plug is not inserted, the through hole 313 is not connected to the grounding hole. When the three-prong plug is inserted, the longer grounding prong is inserted first and abuts against the traction inclined wall 314, causing the large end 301 to slide toward the first end. At the same time, the grounding prong slides down along the traction inclined wall 314 until the three-hole protective door 3 completely exposes the three holes, thus realizing the insertion of the three-prong plug.

[0040] Specifically, the bottom of the frame 1 is provided with a support boss 11 and a stop boss 14, and a stepped shoulder is formed at the connection between the large end 301 and the small end 302 of the three-hole protective door 3. The support boss 11 extends from the first end to the second end. The grounding hole is provided on the support boss 11 and the length direction of the grounding hole extends along the length direction of the support boss 11. The three-hole protective door 3 is slidably mounted on the support boss 11, and the height of the stop boss 14 is less than or equal to the height of the support boss 11. The stop boss 14 can restrict the large end 301 from sliding towards the first end. In this embodiment, in order to reduce weight and material usage, the support boss 11 is provided with a groove with a width not less than the width of the grounding hole to meet the requirements of supporting the three-hole protective door 3, and at the same time, it is beneficial to improve weight reduction. By setting the support boss 11, the three-hole protective door 3 is spaced apart from the bottom of the receiving groove. When a foreign object is inserted, due to the uneven force on the left and right sides of the large end 301, the large end 301 tilts towards the side where the foreign object is inserted. As a result, the step shoulder on the side where the foreign object is inserted is restricted by the stop boss 14 and cannot slide, thus preventing the foreign object from being inserted into the three-hole assembly 102. When the three-hole plug is inserted, the grounding pin abuts against the traction inclined wall 314, meaning that the force exerted by the three-hole plug on the three-hole protective door 3 will not cause the three-hole protective door 3 to deflect. Therefore, when the three-hole plug is inserted, the three-hole protective door 3 can normally expose the corresponding three-hole assembly 102, allowing the three-hole plug to be inserted normally.

[0041] Furthermore, such as Figure 3 and Figure 9 As shown, a mating block 312 is also provided on the small end 302, and a through hole 313 is located on the mating block 312, thereby ensuring that the live wire and neutral wire of the three-prong plug will not contact the large end 301 and cause interference when the ground wire prong of the three-prong plug pushes the three-hole protective door 3 to slide. Please refer to Figures 7-8As shown, the double-hole protective door 2 includes a mating part 21 and protective parts 22 located on both sides of the mating part 21. The two protective parts 22 are used to block the live wire socket and the neutral wire socket of the double-socket assembly 101, respectively. The mating part 21 is slidably fitted onto the mating block 312. The mating part 21 has a through hole 211, which communicates with the through hole 313. When the three-prong plug is inserted, the ground wire prong of the three-prong plug passes through the through hole 211 and abuts against the traction inclined wall 314. Along the direction from the first end to the second end, the upper surface of the protective part 22 of the double-hole protective door 2 extends obliquely upward to form a pushing inclined wall 221. When the double-socket plug is inserted, the neutral wire prong of the double-socket plug abuts against the two pushing inclined walls 221 respectively and pushes the double-hole protective door 2 to slide towards the second end to expose the double-socket assembly 101, so that the double-socket plug can be inserted smoothly.

[0042] Specifically, the mating block 312 has a mating surface 3121, and the inner surface of the mating groove 212 can slide with the mating surface 3121, creating a gap between the bottom of the double-hole protective door 2 and the bottom plate 31 of the three-hole protective door 3. When the double-hole protective door 2 and the three-hole protective door 3 abut against the first end and the second end respectively, that is, when the double-hole protective door 2 and the three-hole protective door 3 simultaneously block the corresponding double-hole group 101 and triple-hole group 102, the protective part 22 is spaced apart from the large end 301 along the direction from the first end to the second end. Since the mating block 312 has a through hole 313, the mating surface 3121 of the mating block 312 is the outer surface of the top of the mating block 312 without the through hole 313. When the inner surface of the mating groove 212 slides with the mating surface 3121, the mating surface 3121 of the mating block 312 provides support for the double-hole protective door 2, and at this time, there is a gap between the double-hole protective door 2 and the bottom plate 31. When a foreign object is inserted, it abuts against the push-sloping wall 221 of one of the protective parts 22. Due to the uneven force on the left and right sides of the double-hole protective door 2, the protective part 22 on the side with the foreign object inserted tilts downward and slides towards the second end. At this time, the large end 301 of the base plate 31 limits it to prevent the foreign object from being inserted into the corresponding socket. When the double-hole plug is inserted, the two prongs abut against the two push-sloping walls 221 respectively. While pushing the double-hole protective door 2 to slide towards the second end, the two prongs slide downward relative to the push-sloping wall 221. The force on the left and right sides of the double-hole protective door 2 is approximately equal, and it will not tilt significantly to one side. This avoids the large end 301 of the three-hole protective door 3 restricting its sliding, thus allowing the corresponding double-hole group 101 to be exposed normally, so that the double-hole plug can be inserted normally.

[0043] Optionally, to ensure that the protective part 22 can effectively block the double socket group 101 when a foreign object is inserted, the ratio between the distance between the protective part 22 and the large end 301 and the length of the double socket group 101 along the direction from the first end to the second end is less than 0.3.

[0044] Furthermore, a sliding groove 213 communicating with the mating groove 212 is provided at the bottom of the mating part 21, and a sliding boss 311 is also provided on the bottom plate 31 of the three-hole protective door 3, extending from the first end to the second end. During the insertion of the double plug, after the inner surface of the mating groove 212 slides to disengage from the mating surface 3121, the height of the upper surface of the mating block 312 decreases due to the through hole 313, so the double-hole protective door 2 falls a certain distance. At this time, the sliding groove 213 and the sliding boss 311 slide and engage, providing guidance for the movement of the double-hole protective door 2. That is, during the insertion of the double plug, the mating block 312 first provides guidance, and then the sliding boss 311 provides guidance, to avoid deviation during the sliding process, which would prevent the double plug from being pulled out and unable to be reset smoothly.

[0045] Optionally, such as Figures 1-4 As shown, frame 1 is provided with a limiting boss 12, and double-hole protective door 2 is provided with a first anti-detachment boss 222. When double-hole protective door 2 abuts against the first end, the first anti-detachment boss 222 can cooperate with the limiting boss 12 to prevent double-hole protective door 2 from falling out of the receiving groove. Frame 1 is also provided with a limiting hole 13. Three-hole protective door 3 is provided with a tailstock 32 at the second end of the base plate 31 near the receiving groove. The tailstock 32 is provided with a second anti-detachment boss 322. When three-hole protective door 3 abuts against the second end, the second anti-detachment boss 322 can cooperate with the limiting hole 13 to prevent three-hole protective door 3 from falling out of the receiving groove. The mating part 21 of double-hole protective door 2 is provided with a first mounting boss 214 at the end facing three-hole protective door 3, and the tailstock 32 of three-hole protective door 3 is provided with a second mounting boss 321 at the end facing double-hole protective door 2. In this embodiment, the elastic element 4 is preferably a helical spring. The two ends of the helical spring are respectively sleeved on the first mounting boss 214 and the second mounting boss 321. The helical spring is always in a compressed state to ensure that the double-hole protective door 2 and the three-hole protective door 3 are respectively abutted against the first end and the second end of the receiving groove. At the same time, after the double plug or the three plug is pulled out, the elastic force of the helical spring pushes the corresponding double-hole protective door 2 or three-hole protective door 3 to reset.

[0046] This embodiment provides a socket, including the protective structure described in the above embodiments. The socket in this embodiment is a combination five-hole socket or a multi-functional socket with combination five-hole sockets. By incorporating the protective structure in this embodiment, the socket is made smaller.

[0047] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
